RenderWindow does not close with vtk-9.0.0 on Ubuntu 18.04

Hello,

The render window does not close out when running the following with Python 3.7.7 using the wheel vtk-9.0.0-cp37-cp37m-linux_x86_64.whl on Ubuntu 18.04.

import vtk

arrowSource = vtk.vtkArrowSource()

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(arrowSource.GetOutputPort())
actor = vtk.vtkActor()
actor.SetMapper(mapper)

renderer = vtk.vtkRenderer()
renderer.AddActor(actor)

renderWindow = vtk.vtkRenderWindow()
renderWindow.SetWindowName("Arrow")
renderWindow.AddRenderer(renderer)

renderWindowInteractor = vtk.vtkRenderWindowInteractor()
renderWindowInteractor.SetRenderWindow(renderWindow)
renderWindowInteractor.Start()

renderWindow.Finalize()
del renderWindowInteractor, renderWindow

Render window also fails to close when using conda-forge/linux-64::vtk-9.0.0-no_osmesa_py38hc86227b_100 on Python 3.8.3 on anaconda on Ubuntu 18.04

The render window closes correctly on Mac OS with vtk 9.0.0, and Linux with vtk==8.1.2.

Thanks for your hard work getting this last release out!

Hello,

Has there been any updates with this issue?

@ben.boeckel Can you think of any reason why Ubuntu 18.04 would be unique?

Sounds like a @ken-martin question since it seems like more of an X thing to me. Does it work on other Linux distros (things have changed so much since 8.1.2 I don't think it's a useful comparison here)?

I can reproduce the window-non-close behavior in Ubuntu 20.04 + Python 3.8 with the VTK 9.0.0 wheel from vtk.org/download.

Could someone try not using the interactor and see if the window closes? Ala

import vtk

arrowSource = vtk.vtkArrowSource()

mapper = vtk.vtkPolyDataMapper()
mapper.SetInputConnection(arrowSource.GetOutputPort())
actor = vtk.vtkActor()
actor.SetMapper(mapper)

renderer = vtk.vtkRenderer()
renderer.AddActor(actor)

renderWindow = vtk.vtkRenderWindow()
renderWindow.SetWindowName("Arrow")
renderWindow.AddRenderer(renderer)

for i in range(300):
  renderer.GetActiveCamera().Azimuth(1)
  renderWindow.Render()

renderWindow.Finalize()
del renderWindow

Indeed that closes just fine after the rendering is done (Ubuntu 20.04 Python 3.8)

Well that helps narrow it down. Something in the XRenderWindowInteractor is messing it up. I'll try getting some display time on a linux system soon and see if I can reproduce it and debug it.

Will be fixed by !7095 (merged)

I believe this specific issue is fixed. If not please reopen.
